Healthcare You Can Wear

Not far away in the same city, a team of students at Northeastern University has combined medical and web-based technologies to create an intelligent T-shirt that can dynamically track a person's workout.

The shirt -- called “squid” because of the EMG (electromyography) tentacles that are sewn into it -- integrates with a smartphone application and a web database to monitor the levels of activation of a person's muscles while engaged in resistance training. To monitor activity, the tentacles stretch from the shirt and attach to a person's chest to measure muscle usage. The shirt also has a heart rate monitor to provide a more holistic view of activity level.

Wellness without the cost
Keeping people fit and healthy is the idea behind one of the early adopters of Vancive's wearable sensor, but from an overall weight-management perspective rather than merely by monitoring their physical activity.

For 13 years, Body Media, based in Pittsburgh, has been helping people manage their lifestyles with sensors designed to be worn on the upper arm. The company partners with 24 Hour Fitness, Jenny Craig, and other weight-management affiliates to help people keep track of what they’re eating, their physical activity, and sleep levels to see how it affects their weight and health.

Body Media’s patch, which uses Vancive's wearable sensor technology, is worn on the upper arm and used in lifestyle and weight-management solutions. The patch is designed to be used on a trial basis for a fraction of what the company’s sensor solutions usually cost, so people can experiment with the technology.

“We use multisensors to make more accurate statements about the body,” Ivo Stivoric, co-founder and CTO of Body Media, told Design News. “If you’re doing lifestyle management or you’re logging your food, you want to know what it’s going to be like [after you eat it] and why it’s going to be the way it is.”

Typically, people using Body Media’s technology are in long-term health and weight-management programs that require contractual commitments and cost a considerable amount of money, such as $100 or more, Stivoric said. The sensors are also attached with fabric straps around the upper arm rather than through an adhesive, making the system itself built to last rather than disposable.

In 2011, the company sought a way to bring its technology to the masses so people could experiment with their wearable sensors on a trial basis, using a temporary adhesive system into which it could integrate its sensor platform. Body Media’s technology features an accelerometer, a motion sensor, and a thermometer, as well as sensors to measure dynamic skin response, the amount a person is perspiring, and other physical activity, Stivoric told us.

That’s where Vancive came into the picture. "We went on a search for a partner with adhesives that can last for seven days,” he said, allowing people to track their lifestyle for a week to see if a longer-term program is something they’re interested in. “For 30 to 35 bucks, you grab a patch, slap it on your arm for a week, and at the end of the week you see a report of your lifestyle."

To download the information, the patch has a USB connector that can be attached to a computer or other USB-compatible device for viewing, though eventually, Body Media plans to add wireless connectivity to its patch, which is expected be on the market early this year.

Tim, my major concern is also in similar line. How it’s communicating with Doctor and is this communication channels are secure enough. Otherwise adding extra noises in channel make interpolate the sensor datas and lead to a misreading.

Notarboca, I think HIPPA rules only cover about the datas in repository. I mean the content of health data repository and as of now this sensor communication won't comes under the preview of such laws. If needed federal government can take necessary steps to bring all such things under an umbrella, that's all.

These systems could use the bendable lithium-ion batteries that Elizabeth wrote about in the link below. Flexible patches for insulin delivery and cardiac monitoring seem like perfect applications for bendable batteries.

Charles, thanks for the link. If am not wrong, such insulin pump and cardiac monitoring devices are not communicating with any external devices. It's a self monitoring and correcting devices. So there is no need of any remote communication.

Elizabeth.. very nice article. I'm coming to the party late but still wanted to give my .02. The ingestible sensors are very interesting however I'm not sure I would want to take one of the pills.

I like the no battery and antenna approach that uses the stomach's fluid for power source and the body to transmit. The patch looks somewhat large but guess as time goes on it will get smaller and smaller....

It won't be too much longer and hardware design, as we used to know it, will be remembered alongside the slide rule and the Karnaugh map. You will need to move beyond those familiar bits and bytes into the new world of software centric design.

People who want to take advantage of solar energy in their homes no longer need to install a bolt-on solar-panel system atop their houses -- they can integrate solar-energy-harvesting shingles directing into an existing or new roof instead.

Kaspersky Labs indicated at its February meeting that cyber attacks are far more sophisticated than previous thought. It turns out even air-gapping (disconnecting computers from the Internet to protect against cyber intrusion) isn’t a foolproof way to avoid getting hacked. And Kaspersky implied the NSA is the smartest attacker.
